can anyone help -- i am pulling my hair out
i have 2 sets of radio head mics
one is a samson the other is audio technica and for some reason i cant get them to make a sound----they are powering up fine and when a mate of mine tested them on an oscilloscope they are working but not a peep from them
any help or guidance would be greatly appreciated

Are they condensor mics? If so you'll need phantom power on your desk.

Have you checked the reciever and transmitter are both on the same frequency as this is normally changable. Also check they do not hve a mute button somewhere on them as soem radio mic have tham as well. And then obviously check the reciever is correctly plugged into your mixer on the correct channel and the channel is working.

i have done all that -- bar the frequency bit ----- as both headsets and receivers seem to have screw setings on them ---- can this be done by trial and error or is it a job for a proffesional ???
many thanks for the advice
